Signs You’re Low on Vitamin B12
For personalized guidance, consult your healthcare provider, registered dietitian nutritionist (RD or RDN), or pharmacist. The assessment of riboflavin status is essential for confirming cases with non-specific symptoms whenever deficiency is suspected. When excess riboflavin is absorbed by the small intestine, it is quickly removed from the blood and excreted in urine. Urine color is used as a hydration status biomarker and, under normal conditions, correlates with urine specific gravity and urine osmolality. However, riboflavin supplementation in large excess of requirements causes urine to appear more yellow than normal.
Eye Fatigue
There are rare genetic defects that compromise riboflavin absorption, transport, metabolism or use by flavoproteins. One of these is riboflavin transporter deficiency, previously known as Brown–Vialetto–Van Laere syndrome. When untreated, infants with riboflavin transporter deficiency have labored breathing and are at risk of dying in the first decade of life. People at risk of having low riboflavin levels include alcoholics, vegetarian athletes, and practitioners of veganism. Pregnant or lactating women and their infants may also be at risk, if the mother avoids meat and dairy products.
